5. Grappling Hook
A staple in Link's arsenal, this gadget is used to cross wide gaps. After firing it, it attaches to any non-rocky surface and pulls Link to that spot. It can be used to climb many areas but also as a weapon to "pull away" Morpha' s (a giant amoeba) eye in the Water Temple.
This is the gadget that Solid Snake uses in MGS4. It's a nano-suit which perfectly blends with the environment in a few seconds. Essential in most parts of the game (especially in harder difficulties) to sneak between the soldier patrols even in highly illuminated areas.
3. Portal Gun
A genius gadget used in the game "Portal". This weapon/tool creates portals in a wall which you can enter to be transported to a completely different place. The key here is that you keep the momentum and speed when you enter the first portal, so you can use it to reach seemingly inaccessible areas by running and jumping.
But remember, the cake is a lie!
Definitely worthy of the second spot in this list of the top 20 computer game gadgets.
Where would Pokemon Trainers store their beloved animal-fighters if it weren't for this marvelous piece of technology? Throw a Pokéball at a Pokemon and (if it's weak enough) the Pokéball will capture it, then you can use the newly acquired Pokémon to fight against other Pokémon trainers. The Pokéball is really small too so it's very easy to carry it in any kind of backpack!
1. Gravity Gun
This is the number one computer game gadget for a reason. It completely changed the way you played the videogame, making you able to use the environment in a smart way to kill your enemies in imaginative ways. For example, by grabbing a saw and throwing it to an enemy to cut it's head off.
It has been copied in many games (like Bioshock) where the Gravity Gun takes the form of a plasmid power which lets you return fireballs to their owners, lift heavy objects or even solve some complicated puzzles.
